How to refresh or flush Domain Name System(DNS) Cache in windows

So you have modified your nameserver details of your domain but still it looks like it is not updated as the site still points to the old name server..frustrated ..?

This mainly happens due to Domain Name System (DNS) cache which still points the site to the old name server.In order to flush or reset DNS cache in windows open command prompt and type ipconfig /flushdns and press enter

Note : Sometimes the delay is due to the domain registrar DNS server itself and in that case nothing can be done :)
